Research on baby sign language has found that teaching baby signs improved cognitive and emotional development. Far from slowing down speech, baby sign language actually increases the rate of verbal development and at the same time increases the parent/child bond.
The most significant research was an NIH funded study comparing two groups of 11 month old babies. One group was taught baby sign language. The second group was given verbal training. Surprisingly, the signing group were more advanced talkers than the group given verbal training. The lead of the signing group continued to grow, with the signers exhibiting verbal skills 3 months ahead of the non-signers at 2 years old. Their lead seemed to shrink a little after two years old, but even at three years old – the signers were still ahead1.
The authors of the NIH study, followed up with the children at 8 years old. Surprisingly, there was still a difference. Signers showed IQ’s 12 points higher than the non-signers, even though they had long since stopped signing. This put the signers in the top-25% of eight year old, compared to the non-signers who were close to average2.
Results like these have led to research on how signing could be used to improve early infant education. This research has turned up a whole host of benefits to signing. Some of these benefits include making mothers feel better about themselves and more “tuned in” to their baby, reducing baby distress, and improving communication between parent and child3.
Now keep in mind that these studies have all been relatively small – the NIH funded study for example had only 100 babies. However, these early results look very promising. These results combined with all the anecdotal reports from signing parents gives a lot of reason to be very optimistic about the results from future baby sign language research.
